Do we need a UDF for transient compressible simulation in Fluent?

I observed in some manuals and websites for performing transient simulation in Fluent that UDF (sinusoidal profile of pressure) has been used at the pressure outlet of the domain. Is it necessary...

Why the solution of a transient flow problem reaching steady state after the flow has evolved in Fluent??

I am simulating a transient supersonic flow in CD nozzle. After the flow has evolved, the solution is reaching steady-state. What might be the reason the reason for it? It seems that with each...

What should be the gauge pressure in pressure outlet bondary condition with Subsonic and Supersonic flow at the pressure outlet?

It is known that the solver only takes the value of gauge pressure only when the flow is subsonic. So what should be the value for gauge pressure?? Should it be ambient pressure?

Why my result is diverging when the low mach number flow is reaching the pressure outlet??

I am doing transient simulation of compressible flow over forward facing step. The pressure ratio maintained is 5.5 bar. Whether it is k-epsilon or k-omega it is diverging only when the low mach...

User Defined Function (UDF) for pressure outlet in Fluent

I want to have a time variation of pressure at the outlet, maybe sinusoidal to do unsteady simulation of compressible flow in nozzle. Could you please share the unsteady_compressible.zip file...
